Description

Detailed Description of the Invention

"Industrial application fields"
Industrial waste can be used for the organic material in the outer shell and the inorganic material in the outer shell. A functional floating ceramic ball floats on the liquid surface and performs its function effectively. Floating ceramic balls and non-oxidizing fired floating ceramic balls coated with photocatalytic titanium oxide are used for the purification of air, water and water pollution. A floating ceramic ball coated with an inorganic fluorescent material is used as a landscape material on the water surface. A floating ceramic ball coated with a graft-polymerized ethylene oxide deodorizer is used to trap liquid odors and bad odors from water.

"Conventional technology"
Since general floating ceramic balls need to have a specific gravity of 1 or less, the entire ball is made floating by forming a number of closed cells inside like a pumice. Conventional floating hollow ceramic balls are manufactured by a mold forming method or a casting method. General ceramic balls coated with photocatalytic titanium oxide have a high specific gravity and are used by being fixedly installed on the bottom of the water.

"Problems to be solved by the invention"
In the conventional manufacturing method, in order to carry out hollow molding, the shape of the shell must be made thick so as to have a certain strength in order to maintain the shape during the molding process. In the production method of the present invention, since the substrate surface is coated, the strength is not required, and the substrate may be thin. Similarly, in the conventional manufacturing method, since it is manufactured using a mold / gypsum mold that matches the outer diameter, only products of that size can be manufactured. It is not easy to change the raw materials. In addition, since it is produced by limiting the number of molds and plaster molds, it is not suitable for mass production.
In the manufacturing method of the present invention, a product having a required size can be manufactured arbitrarily, and mass production can be performed without cost, so that the manufacturing cost can be greatly reduced. In addition, it is easy to change the raw material, and it can handle many kinds of small lots. Since the specific gravity of the ball can be made to the required value simply by changing the amount of the shell material, the float can be positioned on the surface of the water and the range of use can be expanded. The photocatalytic titanium oxide coated on the ceramic ball is activated by the irradiation of sunlight and fluorescent light, and decomposes organic pollutants. The specific gravity is heavy, and the conventional surface that is fixedly installed has a limited irradiation surface. The ball is made easy to move, and a floating ceramic ball is irradiated with light on the entire surface.

"Means to be Solved by the Invention"
Get any small sphere as the central core. Regardless of material, appearance and quality. While rotating the required number of small spheres, organic particles or organic particles as a percentage are mixed with inorganic particles and coated to the desired size using water as a medium. The outer shell is coated with an inorganic material using water as a medium. Thereafter, drying is performed. If heating is continued at 200 to 450 ° C. for the entire amount in the firing process, part or most of the organic matter inside becomes gasified and becomes a cavity. Further, the temperature of the outer shell is raised to the optimum temperature for the inorganic material. The finished ball is lighter and completes the production of floating ceramic balls.

"The invention's effect"
The functional ceramic ball floats on the liquid surface and works effectively against the liquid due to its function. The ceramic balls coated with titanium oxide are purified by the irradiation of sunlight and fluorescent light. It also decomposes and purifies organic pollutants on the surface and water. A ball manufactured by non-oxidizing firing has both an adsorption function by charcoal and a photocatalytic action. Ceramic balls coated with a fluorescent material can be used as a landscape material when irradiated with black light. The ceramic balls coated with the graft polymerization ethylene oxide deodorizer capture the odor of the liquid and the gases that are generated at the bottom of the water. Since these ceramic balls can easily adjust the specific gravity in the manufacturing process, the position of the floating of the water surface can be appropriately set. In the above floating ceramic balls, the spheres are actively moved by a slight wind, water flow, and movement, and the effects of their functions are fully exhibited. There are rivers, ponds, irrigation canals, outdoor pools, water supply plants, sewage treatment plants, aquaculture ponds, bathtubs, etc. Since it is easy to manufacture by changing the diameter and material of the sphere, it can be used for many types of small lots. The sphere filled flat in a fibrous net bag can be collected and replaced at a time, and the workability is good.
